Answer
The different terms used in the Bible for heaven and hell—sheol, hades, gehenna, the lake of fire, paradise, and Abraham’s bosom—are the subject of some debate and can be hard to keep straight.
The word paradise is used as a synonym for heaven (2 Corinthians 12:3–4; Revelation 2:7). When Jesus was dying on the cross and one of the thieves being crucified with Him asked Him for mercy, Jesus replied, “Truly I tell you, today you will be with me in paradise” (Luke 23:43). Jesus knew that His death was imminent and that He would soon be in heaven with His Father. In His words of comfort to the penitent thief, Jesus used paradise as a synonym for heaven, and the word has come to be associated with any place of ideal loveliness and delight.
Abraham’s bosom is referred to only once in the Bible—in the story of Lazarus and the rich man (Luke 16:19–31). Abraham’s lap was used in the Talmud as a synonym for heaven (Seder Nashim, Kiddushin 72b). The image in Jesus’ story is of Lazarus reclining at a table leaning on Abraham’s breast at the heavenly banquet—as John leaned on Jesus’ breast at the Last Supper. The point of the story is that wicked men will see the righteous in a happy state, while they themselves are in torment, and that a “great gulf” that can never be spanned exists between them (Luke 16:26). Abraham’s bosom is obviously a place of peace, rest, and joy after death—paradise.
In the Hebrew Scriptures, the word used to denote the realm of the dead is sheol. It simply means “the place of the dead” or “the place of departed souls/spirits.” The New Testament Greek equivalent to sheol is hades, which is also a general reference to “the place of the dead.” Sheol/hades is divided into a place of blessing (where Lazarus was in Luke 16) and a place of torment (where the rich man was in Luke 16). Sheol also seems to be a temporary place where souls are kept as they await the final resurrection. The souls of the righteous, at death, go directly into the presence of God—the part of sheol called “heaven,” “paradise,” or “Abraham’s bosom” (Luke 23:43; 2 Corinthians 5:8; Philippians 1:23).
The Greek word gehenna is used in the New Testament for “hell” (see Matthew 5:29; 23:33). The word is derived from the Hebrew word ge-hinnom, which designated a valley south of Jerusalem—a cursed place that had been the site of human sacrifice (2 Chronicles 28:3; 33:6). Jesus referenced Gehenna as a symbol of the place of judgment after death, alluding to prophecies in Jeremiah 19:6 and Isaiah 30:33.
The lake of fire, mentioned only in Revelation 19:20 and 20:10, 14-15, is the final hell, the place of eternal punishment for all unrepentant rebels, both angelic and human (Matthew 25:41). It is described as a place of burning sulfur, and those in it experience eternal, unspeakable agony of an unrelenting nature (Luke 16:24; Mark 9:45-46). Those in hades/sheol who have rejected Christ will have the lake of fire as their final destination.
But those whose names are written in the Lamb’s book of life should have no fear of this terrible fate. By faith in Christ and His blood shed on the cross for our sins, we are destined to live eternally in the blessed presence of God.
